この発明は骨材と樹脂を混練したものに硬化剤を添加し

関するものである。[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a resin mortar spraying device for adding a curing agent to a mixture of aggregate and resin and spraying the mixture onto a covered object. .
従来のこの種装置として、樹脂モルタルを収容する容器

グ側に搬送しながら主ノズルで噴出させるようになって
いる。As a conventional device of this type, there is a portable continuous spray device that includes a container containing resin mortar and a main nozzle attached to the outlet of the container via a housing. That is, in this spraying device, a resin mortar made by thoroughly kneading aggregate such as silica sand, thermosetting resin such as acrylic resin, and hardening agent such as organic peroxide is put into the container,
The resin mortar in this container is conveyed to the housing side using air pressure or the like and is ejected from the main nozzle.

することになる。However, in the above configuration, since the kneaded mixture of aggregate, resin, and curing agent is put into the container, the resin mortar hardens over time, causing damage to the inner walls and openings of the container. There is a risk of clogging the main nozzle. If the main nozzle becomes clogged, cleaning will be time-consuming and will hinder the spraying process. It may be possible to select a curing agent with a long curing time, but in that case, the curing period of the resin mortar sprayed onto the object will be long (and the free time before the next process will be extended). As a result, the workability of spraying will be significantly reduced.
この発明は上記従来のものの問題点を解消するためにな

供することを目的としている。This invention was made in order to solve the above-mentioned problems of the conventional method, and by supplying the curing agent to the main nozzle through a route different from that of the kneaded material of aggregate and resin, clogging of the main nozzle can be prevented. It is an object of the present invention to provide a device for spraying resin mortar that can be reliably prevented.

ルを上記ハウジングに設けたものである。The apparatus for spraying resin mortar according to the present invention connects a main nozzle via a housing to a discharge port formed in a container containing a mixture of aggregate and resin, and connects an inner pipe for supplying a hardening agent and a compressor. The housing is provided with a curing agent feeding nozzle, which is composed of an outer pipe for feeding air, and which adds and mixes a curing agent to the kneaded material near the main nozzle in the housing, and feeds the mixture to the main nozzle. .

Since the resin mortar is fed, it is smoothly ejected from the main nozzle without hardening.

つぎに、上記構成の動作について説明する。Next, the operation of the above configuration will be explained.

状の熱硬化性樹脂、たとえばアクリル樹脂を使用する。First, a kneaded material M of aggregate and resin is prepared. The mixing ratio of the aggregate and the resin is, for example, 80 parts by weight of the aggregate and 20 parts by weight of the resin. This mixing ratio may be such that the aggregate content is usually 60% or more. As the aggregate, for example, silica sand (Sin, powder) is used. In addition, conventionally known materials such as ceramic powder and converter slag can be widely used. The particle size is generally about 4
It is sufficient that the particle size is less than 1, usually about 1 fin, and has a particle size of what is called a so-called fine aggregate. Further, as the resin, a liquid thermosetting resin, such as an acrylic resin, is used.

給される。On the other hand, curing agent N is continuously supplied by a metering pump. As the curing agent N, for example, an organic peroxide or an amine is used. The curing agent N supplied from the metering pump is continuously fed into the inner pipe 10 of the curing agent feeding nozzle 8 via the switching valve 19 according to the amount adjusted by the curing agent adjustment valve 23 . At the same time, compressed air A is supplied from the compressor. The compressed air A is 3.5-4 kg/crA at the air regulating valve 14 of the air valve device 15.
After the pressure is adjusted to a certain level, it is fed to the outer pipe 1) of the nozzle 8 via the hose 13 and the mating member 12.

ことができる。The curing agent N and air A are discharged from the tips of the inner pipe 10 and the outer pipe 1) of the curing agent feeding nozzle 8, respectively. That is, when the compressed air A is released from the outer pipe 1), the inside of the compressed air A becomes negative pressure due to the venturi action, and the hardening agent N in the inner pipe 10 is vigorously drawn out. For this reason, the curing agent N is added to and mixed with the aggregate and resin kneaded material M discharged into the housing 4, and the hardening agent N is added and mixed into the mixture M of aggregate and resin discharged into the housing 4, and is vigorously delivered to the main nozzle 5 by the ejection force of the compressed air A from the vicinity of the main nozzle 5. will be sent. As a result, the resin mortar Q in which the hardening agent N is added to the kneaded material M is ejected from the main nozzle 5, and spraying work can be performed.

行うことができる。Here, since the curing agent N is fed to the main nozzle 5 together with the compressed air A from the vicinity of the main nozzle by a route different from the feeding route of the kneaded material M of aggregate and resin, the kneaded material M etc. are fed into the container. Since the hardening agent N is not hardened and adheres to the discharge port 3 of the resin mortar 1, and the hardening agent N is also discharged near the main nozzle 5, there is no risk of clogging the main nozzle 5, etc., and continuous resin mortar is removed. Q can be sprayed satisfactorily over a long period of time.
ところで、上記硬化剤送給ノズル８の内側パイプ１０に

That is, by switching the valve portion 19d of the switching valve 19 from the solid line position to the dotted line position in FIG. 4 to cut off the supply of the curing agent N, and opening the air valve 20, the compressed air A is used as cleaning air. Hose 21 and switching valve 1
9 and is fed into the inner pipe 10 for feeding the curing agent, so that the kneaded material M flowing back into the inner pipe 10 is discharged forward and cleaned.

Since the curing agent is added to and mixed with the kneaded material near the main nozzle and then fed to the main nozzle, the risk of the kneaded material curing and adhering to the container or clogging the main nozzle is eliminated, and the resin The workability of mortar spraying can be greatly improved.
